If you are at a place where the food is on display (cafe/food court and the like), and you have a large crowd of children, don't line them up in front of the food display, or even have them sitting on the display. Preferably take them and have them seated so other people can choose what they want and order while you are placing your enormous order, instead of them having to weightloss 10+ mins to (finally) order.
